Japanese beer maker Asahi disclosed Thursday that a September ransomware attack potentially exposed personal information of over 1.5 million customers. The cyber-attack, claimed by ransomware group Qilin, crippled operations across Japan's factories and forced employees to process orders with pen and paper. The breach affected customer names, addresses, and contact details from service centers, plus data from 107,000 current and former employees and 168,000 family members. Credit card information wasn't compromised. The attack caused widespread drink shortages across Japan, where Asahi controls 40% of the beer market. Asahi spent two months containing the breach and is delaying financial results to focus on recovery efforts. **Source:** [BBC](https://www.bbc.com/news/articles/ce86n44178no)
